The processing procedure is of essential influence when considering quality and hygienic security of an agricultural product. Inadequate treatment is the main reason for quality losses. The working conditions decisively influence the microbiological quality of the process. Extend of physiological damage, change of the biochemical composition, and progress of microbiological degradation depend directly on the kind of treatment. The continuous use of the same cutting tools without cleaning- reduces the quality of the product through microbiologic contamination. Therefore a method of processing is introduced and replaces the traditional cutting tools and their associated drawbacks by a high pressure water-jet. Furthermore the combination of water-jet cutting, image processing, and robotics facilitate anatomically optimized peeling of a body. This leads to a significant reduction of off-cuts.
